SIDE-HILL PLOW A SPECIFICATION forming part of Letters Application filed May 11, 1887.

.To all whom, 2'15 may concern:

Be it known that I, ELISHA CLARK, of Felton, Santa Cruz county, State of California, have invented an Improvement in Side-Hill Plows'and Road-Graders; and I hereby declare the following to be a full, clear, and exact do- My invention. relates to an improved sidehill or reversible plow which may also be employed as a road grader.

It consists of a plow-beam united to a landside or shoe at the bottom by means of a vertical post or posts, and having the mold-board and plowshare supported in front of the post by a. vertical shaft or spindle, about which it may turn so as to stand upon either side of the plow'beam and with either point toward the latter being formed upon the front of the stationary shoe before described.

Referring to the accompanyingdrawings for a more complete explanation of my invention, Figure 1 is a view of my plow, showing the mold-board upon one side and the plow acting asa right-hand plow. Fig. 2 is a plan view with the beam removed,showing therelative position of the parts and the plow reversed. Fig. 3 is a view of my additional shoe.

In the present case I have shown my plow in the single form, having the plow-beam A and a long shoe or landside, B, standing in line beneath the beam and united thereto by the vertical post 0 and holding-bolt D. The plow-point E is formed upon the front end of this shoe or landside and corresponds with either point of the mold-board when it is turned to connect with the point. The moldboard F is curved and formed in any suitable manner,having the points G and H at the op posite lower ends. To the upper rear part ofthe moldboard is bolted an iron frame, I, and to the lower part another iron frame, J, the ends of the two being bolted securely to the rear of the mold-board, so as to hold it. Through the central portions of these frames and behind the center of the moldboard a standard or spindle, K, passes, the lower end being secured to the shoe or landside, and the upper passing up through the plow-beam A, to which it may be secured by a nut, as shown.

ard or spindle freely, so that either point may be swung around and stand in line with the plow-point- E and act in connection with it to board then corresponds. Byswingingthe moldboard about this central standard the other endcoincides with the plow -point and the soil is thrown to the opposite side.

No fastening is necessary to hold the mold board in place, as the pressure of the earth upon its front holds it without other assistance.

In order to properly divide the soil for the mold-board I employ a colter, L, which extends from the plow-beam down to the plowpoint, being secured at both ends,.and it then serves the additional purpose of a brace to strengthen the shoe or landside and prevent its being bent or twisted out of place by striking roots or stones. This is necessary because of the great distance from the vertical post which unites it with the plow-beam.

In order to make the connection between the point and the plow-beam so that the colter can be easily removed,aholeis madein the rear porcurves backward, and the lower part of the colter is formed with a sort ofhook which enters this baekwardlycurved opening, and, when the colter is turned up so thatits upper end is in proper place with .relation to the plow-beam, this hook holds the plow-point securely. The eolter is then held at its upper suitable means.

\Vhen it is desired to throw the furrow uphill, as it is impossible to prevent the plow from sliding downhill with the ordinary flat landside or shoe, I make aspecial shoe which, as is shown in Fig. 3, is of considerable depth, .being as much as two or threeinches, and this is fixed to the lower end of the vertical post in the same manner as the ordinary fiat shoe. This holds the plow upon the soil and prevents its slipping sidewise, while at the same time it is held in a vertical position, thus throwing its furrow up the hill. hen the plow is to be used for roadgrading or similar work,it is made of considerable length and will throw the dirt off from an inclined surface, which can thus be very easily leveled andgraded.

The mold-board then turns about this stand- Having thus described my invention, what turn the soil upon the side to which the moldtion of the point, the lower part of whichend by the diagonal strap and bolts or other I claim as new, and desire to secure by Letters Patent, is

1. Areversible plow consisting of a beam, the landside or shoe standing in line below it and rigidly connected therewith,having a single point formed upon its front end, in combination with a double-ended mold-board having its rear and central portion journaled upon a fixed vertical post extending from the plowbeam to the landside or shoe,so that the moldboard may swing across the front of the landside to stand upon either side, with the points engaging a corresponding slot or groove made in the plow-point, substantially as described.

2. A reversible plow consisting of the beam, a shoe or landside standing parallel therewith and below it and rigidly united to it by means of the standard at the rear, and a colter having a curve at the lower end which enters the plow-point formed on the front of the shoe, 20 while the other end is secured to the plowbeam, in combination with a mold-board having points at either end which may engage a groove or channel at the rear of the plowpoint, and a vertical post extending from the 25 plow-beam to the shoe to which the rear central portion of the mold-board isjournaled,so that it mayswing across the front beneath the plow-beam to engage either of its points with theplow-point,themold-board standing either 0 at the right or left of the beam, substantially as herein described,

In witness whereofI have hereunto set my hand.
